Embodiment

[0336] Hereinafter, the present invention will be described in more detail using examples, but the present invention is not limited to these examples.

[0337] Examples 1-4 are examples, and Example 5 is a comparative example.

[0338] Each measurement was performed according to the following method.

[0339] [Number average molecular weight (Mn)]

[0340] Using a commercially available GPC measuring device (manufactured by Tosoh Corporation, device name: HLC-8320GPC), the gel of several kinds of monodisperse polystyrene polymers with different degrees of polymerization commercially available as a standard sample for molecular weight measurement was measured. Permeation chromatogram (GPC), based on the relationship between the molecular weight of polystyrene and retention time (retention time), a standard curve was prepared.

[0341] After diluting the sample with tetrahydrofuran to 1.0% by mass and passing it through a 0.5 μm filter, the GPC of the sample was measured using...

Synthetic example 1～3

[0370] [Synthesis examples 1 to 3: Synthesis of ink repellent agents (CA1) to (CA3) and preparation of liquids (CA1-1) to (CA3-1)]

[0371] At 50cm with the mixer 3 0.57 g of the above-mentioned compound (c-11), 1.27 g of the above-mentioned compound (c-21), and 0.74 g of the above-mentioned compound (c-31) were charged into a three-necked flask of a , and a raw material mixture of the ink repellent agent (C1) was obtained. Next, 9.85 g of PGME was thrown into this raw material mixture to prepare a solution (raw material solution).

[0372] At room temperature, 1.33 g of 1.0 mass % phosphoric acid aqueous solution was dripped at the obtained raw material solution as a catalyst, stirring. After completion|finish of dripping, it stirred for 5 more hours, hydrolysis and partial condensation reaction were performed, and (CA1-1) liquid which was the PGME solution containing ink repellent agent (CA1) by 10 mass % was obtained.

[0373] Except having used 1.33 g of raw materials sh...

Synthetic example 4

[0374] [Synthesis example 4: Synthesis of ink repellent agent (CA4) and preparation of (CA4-1) liquid]

[0375] Except having used the said compound (c-32) instead of the said compound (c-31), it carried out similarly to the synthesis example 1, and prepared the raw material solution of the ink repellent agent (CA4).

[0376] 0.93 g of 1.0 mass % nitric acid aqueous solution was dripped at room temperature, stirring in the obtained raw material solution. After completion|finish of dripping, it stirred for 5 more hours, hydrolysis and partial condensation reaction were performed, and (CA4-1) liquid which was the PGME solution containing ink repellent agent (CA4) by 10 mass % was obtained.

Abstract

The present invention provides a positive-type photosensitive resin composition capable of producing an ink repellent excellent in ink repellency even after ultraviolet / ozone irradiation treatment, and provides a partition formed using the resin composition, and an optical element. The positive photosensitive resin composition is excellent in ink repellency and has little residue in dots, and has sufficient storage stability. A positive photosensitive resin composition, a partition wall and an optical element formed using the resin composition, the positive photosensitive resin composition is characterized in that it contains an alkali-soluble resin (A), a photosensitizer (B) and A positive-type photosensitive resin composition of an ink repellent (C), wherein the ink repellent (C) is formed from a partially hydrolyzed condensate of a mixture containing a fluorine-containing hydrolyzable silane compound, and the content of fluorine atoms in the above-mentioned hydrolyzable silane compound is The ratio is 10 to 55% by mass.

Description

technical field [0001] The present invention relates to a positive photosensitive resin composition, a partition formed using the same, and an optical element having the partition. Background technique [0002] As for the partition wall used for the pixel part of the color filter which is an optical element, or an organic EL (Electro-Luminescence) element, the method of apply|coating a photosensitive resin composition on a board|substrate, and forming it by a photolithography technique is known. [0003] In recent years, as a method of manufacturing a pixel portion of a color filter or an organic EL element, a cost-reducing process using an inkjet method has been proposed. [0004] For example, in the manufacture of a color filter, after forming partition walls by photolithography, spray and apply R (red), G (green), and B (blue) ink, and form pixels. [0005] In the inkjet method, it is necessary to prevent color mixing of ink between adjacent pixels. Therefore, the part...
